Writeup from MB 86:

Northwest Africa 974

Remlia, Morocco

Found 2001 April

Enstatite chondrite (E6)

A single stone was found by villagers within 25 km of Remlia, Morocco, and was sold to a meteorite dealer in 2001 April. The original mass was 2250 g, but most of the rusty crust fell off and, therefore, only 1784 g are preseved. Classification and mineralogy (A. Jambon, UPVI): no visible chondrules and no evidence for melting; consists of anhedral enstatite (En>99) and kamacite (Fe93Ni6Si1); minor phases include, plagioclase (Ab82), oldhamite, daubreelite, alabandite, schreibersite, troilite, graphite and silica. Sulfides are oxidized to various degrees. Shock stage, S4. Based on the abundance of kamacite, classification as EH is suggested; yet, compositions of phases are not typical for EH chondrites and are possibly related to the high petrologic grade. Specimens: type specimen, 25 g, UPVI; main mass, Fectay.
